Specification of Letters Patent. Application filed January 16, 1912. Serial No.

To all whom it may concern;

Be it known that I, AUeUsrus G. SNYDER,

a citizen of the United States, residing at Utica, in the county ofOneida and State of New York, have invented or discovered certain new and useful Improvements'inThilL Couplings, of which the following is a specification, reference being had therein to the accompanying drawings.

his invention relates to an anti-rattling thill coupling, and has for its object to provide a coupling of the class referred to, in which the bearing-pin of. the thill iron is yieldinglybut firmly held in place between anti-friction rollers which permit the said pin to be grasped with considerable firmness, so as to prevent rattling, without causing it to bind objectionably.

.In the drawings Figure 1 is a plan View of the improved coupling. Fig. 2 is a side view thereof, and Fig. 3 is a longitudinal section of the same.

Referring-to the drawings, 12 denotes the draft-bar which is adapted to be secured by a suitable clip, as 13, to-the front axle 14 of a' vehicle. The said draft-bar. preferably comprises flanges 15 each of which is reception of the cross bar or draft-pin 17 e an open topped recess in the tion of the draft-bar.

- to a lever 21 a pin 22, p which is riveted or otherwise permanently 20 is connected to oted latch or jaw of the thill-iron 18. The notches 16 provide fixed jaw por- Pivoted to the front ends of the flanges l5is a swinging latch or jaw 19 normally closing the top-of said re.-'

cessand having a slightly upturned portion at its free-end for engagement with a link or bail 20 the .lower end of which is attached pivotally secured, by means of to the front end of a spring 23 ted lines in Fig. 2.

Mounted in the pivotedlatch or jaw .19,

between side flanges with which said latch is provided, is an anti-friction roller 23, andmounted between the flanges 15 of the draft-bar.l2 are two-other anti-friction rollro' vlded with an open to'pped notch 16 for the pin or cross-bar of the thill. ron when-swung upward as denoted by dotopen-topped recess afforded by the notches 16, that the pin .or cross-bar 17 of the thilliron may rest thereon, while the roller 23, carried by the swinging latch or jaw 19, will bear upon the top of the said pin or crossbar, thereby permitting the latter to be clamped between the said anti-friction'roll ers 1n such a manner that it will be held in place with considerable firmness, to prevent rattling, but will still be free to move with the proper freedom without causing too much friction, such as would cause objectionable stiffness or would result in objec tionable wear.

,The anti-friction rollers 23 and 242 are preferably'of hardened steel, and the crossbar or pin of the thill-iron may-likewise be.

of'hardened metal, if desired. Between the flanges 15 extends a bracing or stiffening pin 25 which, when the swinging latch or jaw 19 is in wor 'ng position, is received in notches 26 in said latch, the said pin-thus also serving to steady the said swinging latch or jaw. l j v From the foregoing it will be understood PatentedJune 18, 1912.

- ers 24 which are so disposed, adjacent tothe that the invention provides an anti-rattling thill coupling of convenient construction and eflicient operation, as well as a coupling which will be very durable, in that objectionable wear of the parts is avoided.

Having thus described. my invention I claim nd desire to secure'by Letters Patent:

In a thill coupling, the combination with a-draft iron having a fixed jaw or part comprising side flanges having open-topped notches and provided with anti-friction bearing rollers arranged between said flanges adjacent said notches, of a thill iron having a pin or cross bar adapted to be received in said notches,

against the upper side of said "cross bar or pm and having side flanges between which Copies of this'patent may be obtained for fivelcents each, by addressing the Commissioner of Patents,

" Washington, D. G.

and to bear against. said rollers, a swinging latch or aw-pro-' vided withan anti-friction roller bearlng'
